Method and apparatus for dusting

ABSTRACT

A venturi tube attachment for dusting in extreme conditions. The inner panel is used with the forced air source for the triggering of aspiration through the venturi tube of airborne dust from the ingress opening, a vacuum hose in communication with the atmosphere and the ingress opening by narrow air gap to synergistically combine the features of a forced air component and a vacuum component. The forced air component acting as a trigger at the egress end of the venturi tube to start aspiration through the venturi tube at its ingress end which is in close proximity by narrow air gap to the vacuum hose intake. The aspiration of the venturi draws in airborne dust quickly and from a greater distance than the vacuum component acting alone. The forced air component can be used with the venturi tube alone to direct airborne dust to the floor, open window, or door.

[0001] The application that I am presenting is a Continuation In Part of Ser No. 09/924882 and Provisional No. 60/225932.

FIELD OF THE INVENTION

[0002] The present invention relates to a method and device for suppressing the dust cloud generated by forced air cleaning devices such as leaf blower exhaust tubes, ventilation and abatement systems and compressed air sources, and, more particularly, to the introduction of an externally attached venturi tube bridged between the exhaust path of the forced air component and the intake path of the vacuum component. It is to be use in conjunction with a forced air component and a vacuum component while cleaning dusty areas. It may be used with the forced air component when the vacuum component is deemed unnecessary and only the displacement of dust to the floor is required.

BACKGROUND OF THE INVENTION

[0003] Historically the problem with forced air cleaning/sweeping devices that utilize leaf blower tubes and compressed air cleaning nozzles is that dust is scattered and made airborne to become a problem elsewhere in the environment. Suppression of the dust cloud generated by these devices has not been addressed by sited references. While using forced air devices on sidewalks, parking lots, industrial areas, and granaries dust clouds develop that drift in cross winds. Factory and industrial ventilation systems and any device that relies upon a fan for cooling will draw in airborne dust and clog systems when these forced air devices are used. Operators of these forced air devices and nearby coworkers are subject to breathing in the airborne dust cloud that is stirred up. My method and device suppresses this dust cloud by deflecting the exhaust of the force air component with a venturi tube that aspirates airborne dust from a greater distance than just a vacuum alone could draw. The surrounding atmosphere is recycled back into the direct path of the forced air device exhaust and is also drawn closer to the vacuum nozzle intake. For large dust clouds a higher rate or air pressure/speed would be used, for light dusting a lower rate or air pressure/speed would be used. The dust that becomes airborne is aspirated. This airborne dust is drawn to my venturi tube and into the reach of the vacuum component. When the vacuum component is not used the synergy that develops continues to suppress airborne dust due to the recycling process that occurs. That is, dust particles that bypass the vacuum component are aspirated and recycled, then collide with and suppress new dust particles to suppress them from becoming airborne.

[0004] Solutions of sited references provided rely only on forced air devices intended for other specialized applications such as paper debris, leaves and litter, and not intended to aspirate and dissipate the dust cloud generated by these sited references. None of the sited references have a capacity or were intended to easily aspirate airborne dust.

[0005] It is therefore an object of the invention to suppress airborne dust clouds associated with forced air devices such as leaf blowers, the exhausting port hose of a workshop vacuum, abatement systems, and compressed air devices.

[0006] It is another object of the invention to aspirate airborne dust from a greater distance and into the reach of the vacuum component by powerful aspiration generated through the venturi tube conduit.

[0007] It is another object of the invention to provide a lightweight venturi tube conduit that can be attached to most forced air devices such as leaf blowers, the exhausting port hose of a workshop vacuum, abatement systems, and compressed air devices.

[0008] It is another object of the invention to provide a method of use to suppress the dust cloud generated by forced air devices.

SUMMARY OF THE INVENTION

[0009] In accordance with the present invention, there is provided a venturi tube bridge comprised of a fixed tubular duct member having an ingress opening and an egress opening, an inner panel forced air directing surface adjacent to the egress opening and in communication with the forced air source to triggering aspiration through the venturi tube bridge for the aspiration of airborne dust from the ingress opening, a vacuum component in communication with the atmosphere and the ingress opening of the venturi tube bridge to synergistically combine the features of a forced air component and a vacuum component. The forced air component acting as a trigger at the egress end of the venturi tube bridge to start aspiration through the venturi tube at its ingress end which is in close proximity to the vacuum component intake. The aspiration of the venturi draws in airborne dust from a greater distance than the vacuum component acting alone. This distance will increase in proportion to the force generated by the forced air component. Aspiration of airborne dust will occur and be collected as the dust is drawn in closer into the reach of the vacuum component intake. When the vacuum component is deemed to be unnecessary the forced air component can be used with the venturi tube bridge alone to aspirate airborne dust to the floor, ground, open window or door.

[0047] Referring to FIG. 13 the inner panel forced air directing surface 16 of apparatus is properly positioned by angular support 17 that is attached under the ingress end of the tube body 20 and on top of the adaptive plate 23/platform. The inner panel forced air directing surface 16 receives forced air to direct it downward that when striking dust causes the dust to become airborne. As the forced air slides down the inner panel forced air directing surface 16 a vacuum is created through the tube to the ingress end where aspiration occurs at the ingress opening 19 and anti clog openings 21. Aspirated air is then combined with the forced air source at the egress opening 18 and also introduced to the vacuum hose at the ingress opening 19. The dust cloud is aspirated in part by the vacuum hose and in part by the venturi tube until dust cloud is dissipated.
